Logitech software fails to save settings? Fix here.

So, I’m a gamer.

And I’ve sort of settled on the Logitech series of gaming gear, C920, G213, G602. Running their gaming software (except for the overwolf overlay, I don’t need it, don’t stream).

Something that has kind of been nagging me, on the lower end of reality, is that when I set my mouse DPI, or notification preferences, post-reboot, they all disappeared. So at 5 am this morning I decided to find out why.

The answer is, for some reason, part of the tools installed by Logitech, namely LCore.exe in “C:\Program Files\Logitech Gaming Software”, does not run elevated by default. Why doesn’t it? I don’t know. Why does it need Administrator right? That’s actually a good question. I found tons of ACCESS DENIED events when I reproduced setting the check boxes as I preferred in the

To fix this do the following:

  • press the Windows Key + X
  • Select File Explorer
  • paste C:\Program Files\Logitech Gaming Software in the address bar and hit enter
  • Right click on LCore.exe and select Properties
  • Click the tab Compatibility
  • Check the box for Run As Administrator and click OK
  • Close File Explorer. Reboot.

Now you should have a system that saves your settings you want, like mouse DPI scaling, or button preferences, or not getting a notification Every Single Time you run a game that has a profile!

Proof in the pudding

Procmon showing LCore can’t access/write to its own key structure.

I checked the rights assignment. I tried changing rights on the regkey from the default, but the issue persisted. It probably has other keys it is trying to use, that are not located in HK_Local_Machine, but it’s 6:13 AM and I’m doing this pro bono, so maybe Logitech can noodle the specifics out and make a better installer for next rev.

Here’s what the registry rights were:

  • What up?  Nadda, you?
  • Why did you get lazy and not figure all this out and document it for Logitech?  I’m kinda tired right now, might edit after I sleep again.
  • What is the security impact of running LCore as administrator? It runs as administrator so it can screw stuff up if it gets exploited, etc. This is a design flaw of some kind in how they either 1) packaged the installer or program; or 2) a poorly tested solution. Well, or 3) both.

I personally had this issue, but it’s well documented at many places as a problem;




G303 doesn’t save RGB settings from LogitechG


  1. This is an awful bug that has existed for years. I’ve used 5 Logitech mice over many years across 4 Windows PCs. Logitech Options has never once remembered settings when setting up a new machine. EVER.

  2. How can I save my Logitech G502 Settings on the mouse? I don’t want to use the Logitech Spyw.. I mean G Hub anymore.
